+# GitBucket
+
+GitBucket is the central Git hosting service for the owner's projects.
+
+## Access
+
+- Public URL: `https://git.gnexus.space/`
+- API base URL: `https://git.gnexus.space/api/v3`
+- Repository owner observed: `root`
+- Authentication: personal access token, owner-managed.
+- Secret values are not stored in this repository.
+
+## Infrastructure Path
+
+Public access follows the standard `gnexus.space` route:
+
+`Internet -> external-vps -> OpenVPN tunnel -> internal-proxy-vps -> internal-nginx-proxy -> gitbucket VM`
+
+Known routing:
+
+- Domain: `git.gnexus.space`
+- Internal nginx upstream: `http://192.168.1.156`
+- VM inventory id: `gitbucket`
+- Hypervisor: `hp-proliant-dl380-g6`
+- VM resources: 4 vCPU, 8192 MiB RAM.
+
+## Role
+
+This service is the source of truth for software projects. Agents should use it to:
+
+- discover repositories;
+- connect deployed services to their source repositories;
+- find upstream README/docs/runbooks;
+- identify project ownership, public/private status, and default branches.
+
+Agents should not:
+
+- store access tokens in docs;
+- clone or read secret-bearing files unless explicitly instructed;
+- treat every repository as a deployed service;
+- infer production ownership without deployment evidence.
+
+## Repository Snapshot
+
+Observed through GitBucket API on 2026-05-10.
+
+Total repositories visible to `root`: 65.
+
+Activity labels are based only on last commit date:
+
+- `active-2026`: touched in 2026.
+- `dormant-2025`: last touched in 2025; likely inactive unless deployment evidence says otherwise.
+- `old-2024`: last touched in 2024; treat as abandoned/archive candidate until confirmed.

+
+## Follow-Up Classification
+
+Repositories should be promoted from this catalog into detailed project records when one of these is true:
+
+- the project is deployed on a host or VM;
+- the project owns a public domain or internal endpoint;
+- the project is an infrastructure tool;
+- the project is actively maintained;
+- the project has reusable documentation for other agents.
+
+Useful next groups:
+
+- Gnexus core: `gnexus-auth`, `gnexus-auth-client-py`, `gnexus-auth-client-php`, `gnexus-ui-kit`, `gnexus-book`.
+- Public services: `gnexus-welcome-page`, `lytvak`, `navi-1`, `navi-webclient`, `smart-home-server`.
+- AI/search/media tools: `vec_search`, `duck-search-for-ai`, `web-page-scrubber`, `voice-gen`, `whisper`, `music-parser`.
+- Home/infrastructure tools: `smart-home-server`, `home-web-panel`, `subnet_status`, `upsmon`, `disk-space-api`, `ubuntu_server_scripts`.
+
+## Credential Policy
+
+GitBucket credentials are owner-managed and must not be stored in this repository. If a personal access token is used for documentation work, it should be considered temporary and revoked or rotated after the documentation pass.
